Hi I recently awoke to a zap? It was a loud electrical crackling in my ears and with my eyes closed i could see white electrical like images? All i know is it was loud and it happened as I was falling asleep. It scared me. I told my boyfriend about it and he said possible seizure? I am looking for answers as well.
I do not take any medications except Tylenol and ibuprofen for headaches. I did get a headache the next day. I have been looking at exploding head syndrome but I am not sure if this is what is going on.
More than likely, you suffered from an episode of sleep apnea. You aren't getting enough oxygen so your brain zaps you to wake you up and breathe. Waking up fatigue and with a headache the next day is very common. If you are experiencing this, you need to have a sleep study done. The next time you're zapped, train your self to start taking deep breaths so that you don't have another zap. If you smoke cigarettes, stop. Cigarettes lower blood oxygen levels and can trigger these episodes.
Sleep apnea means that you stop breathing while you are sleeping. For some it's its physical problem blocking their throat. For others, it has to do with brain chemistry. The doctor can supply you with a mask to where that helps.
Interesting reading. I have tried to find info on a similar (but different) condition that happens very infrequently to me but only while while waking up. To explain it, as I wake up, I experience an electrical spark in my head (& perhaps a flash of light but not sure of that). I can then close my eyes & concentrate on creating an image (usually a gallant white horse) and if successful, another spark happens when the image becomes clear. This can be done for 1,2 or 3 times (or not) if I can concentrate effectively after the first. If I get up very soon after the first spark, I can experience it while moving (like to the bathroom) while fully awake but this is less likely. I first worried about it but don't anymore. I'm 78 years old and experience it on only rare occaisions so it's become a game if you will, to see how many times I can effect the spark. If a loud one first, then chances I can effect it 2 or maybe 3 times with each one decreasing in intensity. The sparks have a distinct snaping sound but that's the only sensation. To best describe how I have rationalized the infrequent happening, it's like my brain is in need of some kind of (electrical ?) discharge and the process allows that to happen. Sounds weird but the infrequent happenings are perhaps due to whatever reason of brain activity or REM dreaming that has occurred during my sleep. Anyway, I haven't been able to read of anyone having similar happenings. Most others are of shock, surges, shivers or waves but mostly during or before going to sleep, not specific to waking up.
